Specification of Letters Patent.

Patented Mar. 18,1913.

To all whom it may concern:

Be it known that we, GRANT SIPP and WILLIAM S. WELLS, citizens of theUnited States,,and residents of Paterson, Passaic county,-New Jersey,and borough of Fountain Hill, Lehigh county, and State of Pennsylvania,respectively, have invented certain new and useful- Improvements inQuilling-Machines; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and usethesame, reference being had to the accompanying drawings, which form apart of this specification.

Our present invention relatesto winding machines and particularly tomachines for winding cops, quills and the like.

In the U. S. Letters Patent No. -739;523, granted to W. S. Wells, atension deviceis disclosed which practice has demonstrated permits thethread to be advanced at practically any speed, regular or irregular,which it is desired to impose and yet reserve the tension constant andthe threa intact.

Our principal object in the present instance is to provide a windingmachine employingsuch a tension device, which w1ll be capable ofadvancing the thread and efi'ecting the winding thereof in quills, copsor the like at a much higher speed than has heretofore been possible,whereby to increase the output. v

Other objects are to improve the product, make it possible to change thecharacter of the wind at will, reduce the amount of power whichisrequired to operate the machine capable of ready disassembling andtending to roduce vibration, render the machine capa 1e of readilydisassembling and assembling shouldaccess to any of its working parts benecessary forany reason, and

limit the elements requiring attention on the part of the operator tothe minimum.

While we prefer to employ in the improved machine a tension device ofsubstantially the character of that above. described, it will beunderstood that our invention is not. limited, in any aspect thereof, toan organism including. any particular tension device. I

The invention will be found fully illustrated in eight sheets ofdrawings accompanymg this specification, whereln,

Describing, first, the frame of the machine: a a designate two uprights.forming the ends of the frame and Z) 7) two tie-rods connecting themtogether; 0 c are upper arms and d 02' lower arms projecting laterallyfrom these uprights, the latter supporting a board e on which may be setthe supply spools f, each of which is preferably partly inclosed by atrough-shaped'casing 9, open at thefront, which acts to confine theballooning of the thread. 1

A supporting structure for the various winding units is arranged betweenthe uprights in their upper portions and acts to brace the same and givestability .to the frame as a whole. Said structure comprises theend-frames h h, each of which is bolted to the inner face of an upright,the spindlerails 2' 2', which are secured upon rests j projecting fromthe end-frames, the idlercarryingr rails is k, likewise secured uponrestsl projecting from the end-frames, an upper plate m secured uponrests n projectin from the end-frames, and a lower plate 0 lmposed uponrests p on theend-frames,

said plate 0 having downwardly projecting stiflening flanges g whichbear dlrectly on said restsp. and which are connected at their ends bythewebs 1' notched to receive pins 8 projecting from the end-frames andacting to prevent lateral displacement of the plate 0. In addition,there are the channel-irons t which connect and are secured at theirends to the uprights, each being arranged vertically above thecorresponding spindlerail, and the series of plates u Fig. 23) eachoverlapping one of its neighbors and individually secured to thecorresponding channel-iron and spindle-rail by screws or the like '0 (sothat each may be separately removed upon having access to its screw '0,having removed. a top board to which seats on the strips a, resting onthe channelirons), said seriesof plates serving to close the sides ofthe frame; upon detaching the spindle-rail and channel-iron at eitherside of the machine, the structure comprising these parts and theplates, together with certain portions of the windin units therewithassociated, may be bo ily removed from the machine to afford access tothe working parts.

I To the right-hand upright a is bolted a bracket 3 in which isjournaled the main drive shaft 2, the same being also journaled in theother upright a. The shaft is kept from endwise movement by a pinion 1on its left-hand end in Fig. 1' and a collar 2 on its right-hand end,there being interposed between the collar and braket y on the shaft,fast and loose pulleys 3 around either of which, according to theposition of a beltshifter 4, the driving belt (not shown), may extend.On shaft 2 is splined a cone or conical face plate 5, and bearingagainst the inner side of the c'one 5 is a collar or follower 6 loose onthe shaft and having a flat projection 7 fitting-a slot 8 in ahorizontal lever 9 which is fulcrumed on a bracket 10 on one of the tierods 6 and rests at its handle: end on a toothed bracket 11 carried bythe other. tie rod 6. The bracket 1 affords at 12 a step-bearing for avertical shaft 13 whose upper end'is journaled in a bracket 14 bolted totheadjoining end-frame h (Fig. 2). On shaft 13 is splined a conicalfriction-wheel'15 which bears upon the cone 5. The action of gravityonthe friction-wheel l5 normally tends to cause it to impel the cone tothe left in Fig. 1; and, while the speed of the drive shaft is constant,the

speed of shaft 13 may bevaried according to the position in which lever9 is held (engaged with the toothed bracket 11) and according to thepositions, relatively to each other, which the cone 5 and friction wheel15 assume. Broad claims for this mechanism, per seyhave been reserved byus for a separate application, It may be remarked that the rotation ofthe several spindles is accomplished from shaft 13; he traverse orreciprocating motion of the thread guide is accomplished from shaft 2.

Parallel with shaft 2 and directly below the same is journaled in theuprights a a shaft 16 carrying cams 17 and limited against endwisemovement in its bearings by collars18 engaging the uprights. On itsouter end (Fig. 10) is splined a large spurwheel 19 carrying. on its hub20 a small spurwheel 21 which is secured to the large spurwheel byscrews 22. The hub 20 is formed with a hole 23 to receive a cotter-pin24'which may be introduced into either of two holes 25 in the shaft 16.An intermediate spurwheel 26 is journaled on a sleeve 27 secured to theadjoining upright by a bolt 28, the latter being adjustable in an arcshaed slot 29 in the upright formed about sha. t2 as a center. Thespurwheel 26 is in permanent mesh with'pinion 1 and it serves totransmit rotary motion to shaft 16 at two different speeds, according towhether it is spurwheel 19 br 21 which is in mesh with it.

On the tie rods b are fulcrumed two pairs of levers, each standing inthe vertical plane of a cam 17. One lever 30 in each pair (Fig. 11)carries a roller 30 bearing directly on the cam 17; the other lever 31carries a roller 32 bearing on lever 30 directly above the cam. Bothlevers in each pair have slots 33 and also upwardly projecting arms 34which are connected by a spring 35 operating to press the levers towardthe cam. A bearing block 36 isbolted to the underside of the plate 0 ateach end thereof, each being formed with two half-portions 37 ofbearings whose other half-portions 38 areheld in place by a plate 39secured to the bearing block 36 by a screw 40. In the bearings thusformed are journaled the parallel shafts 41, each carrying two pairs ofoutwardly projecting cranks 42 connected respectivel with the levers 30and 31 by pitmen 43. n the shafts 41 are also arranged outwardlyprojecting arms 43', each having an open bearing 44 at its outer end.The function of these arms will ap ear later.

On shaft 13 is fixed a pulley 45 around which and a pulley 46 at theother end of the machine extends an endless belt 47. The pulley 46 issupported so as to be adjustable to and from pulley 45 to securethe'necessar tension of the belt as follows: A pair of stub shafts 48are fixed in the holes 49 which are formed in'one of the end-frames h(Fig. 20) and on one of these is slipped the sleeveportion 50 of abracket 51 having a stubshaft 52 forming the journal for pulley 46 andalso having a tongue 53 which rests on the other shaft 48. A clampingplate 54 bears at one end against the bracket 51 and at the upper endagainst the shaft on which tongue 53 bears, a screw 55, penetrating theplate and tapped into the bracket, serving to effect the clampingaction.- On each rall 7c is journaled a series of idlers 56 flangedattheir lower ends so as to support the belt.

Neareach longitudinal side of the plate 0 and on the top surface thereofis formed a series of pairs of projections 57 having alined'openbearings 58. In vertical c'oincidence with the projections 57 the platem has a series of pairs of projections 59, the projections in each pairbeing spaced to form a transverse slot or guideway 60. In the bearing 58of each pair of projections 57 are journaled the trunnions 61 of atilting carrier 62, whose upper end has a fin 63 engaged in thecorresponding slot or guideway 60. The spindles 64 are journaled in thebolsters 65 fixed in the spindle-rails z', and the whirl 66 of eachspindle has a V-shaped peripheral groove. Rotary motion is imparted toeach spindle from the belt through a rotary member journaled in thecorresponding carrier 62. This member comprises a spindle 67 and a whirl68 and a friction wheel 69 fixed on the spindle and respectivelyengageable with the belt and the whirl 66; the spindle 67 has a suitablebearing at its upper end in the carrier 62 wardly.

tionally V-shape'd so as to fit the groove in the wheel 66 and spindle67 has slight longitudinal movement in its bearings so that thefriction-wheel may adjust itself to the whirl. In order toset and adjustthe car-' rier from time to time to take up wear between the parts(preserving the whirl and friction wheel in pro er alinement with eachother and the spindle restingon its bearing 70) a set screw 71 is tappedinto the plate 0 under the carrier in engagement therewith, the point ofcontact of the screw with the carrier being slightly inward with respectto the trunnion 61. It will be noted that the whirls 66 and 68 haverelatively less diameter-than the friction-wheel 69, whereby theperipheral speed of the spindle is many times faster than that of, thewhirl 68.

A horizontal shaft 72 extends through the frame, being supported by theupright a.

and 27) which are fulcrumed on this shaft, each standing in the verticalplane of a carrier 62. At its lower end, each bracket has an arm 74 andits upper portion is T- shaped, one arm of the T having-a vertical slot75 and the other being connected with the arm 74 by a vertical rod 76secured by pins to said arms and projecting up- The slotted arm of the Treceives a pin 77 sliding in a bore 78 formed in the correspondingcarrier and cushioned on a spring 79 in said bore. The rod 76 has aseries of holes .80 into any one of which a pivoting pin 81 for a hook82 may be entered. The hook 82 has its hooked portion passed through avertical slot 83 in one of the plates u and adapted to engage a stop .84(formed in two parts clamped to the plate by a screw 85 penetrating theslot), the other end of the hook being a weight 86. The lever structurecomprising the parts 73 and 76, when the hook is released from the stop,as hereinafter described, tends to -73 is one of a series of brackets(Figs. 26 I fall away from the corresponding carrier on the shaft 72 asa fulcrum, such movement being limited by therod 76 engaging the end ofa slot 87 in plate m through which rod 76 projects; the tension of thebelt 47, combined with the action of gravity, causes the carrier 62 tofollow said lever structure, but the movement of the carrier at thistime isbut slight (being preferably sufficient only to break the contactbetween parts 66 and 69) becauset-he spring 79 must first extend itselfto its limit, or substantially so, before the carrier can follow thelever structure. The friction-wheels 69 project through openings 87 inthe plates u.

and being carried by a rail 89 from which depend brackets 90 havinganti-friction rollpresent machine, it is obvious that particu-- ers 91received by the open bearings of the arms 43. Each thread guide rod isarranged at one side of a spindle, and at the otherside thereof andparallel with the rod 88 is an auxiliary guide rod 92 fixed in thechannel iron t and spindle rail 1'. As already stated, the structurecomprising the channel iron, spindle fail, plates u, spindles, and therods 88 and 92 is removable bodily from the frame upon-releasing thechannel iron and spindle rail, the open bearings 44 in the arms 43readil yermitting such removal.

The top building mechanism is shown in Figs. 28, 29 and 30. It comprisesa thread guide member having a'thread' guiding device and carried by therod 88 in such manner as to reciprocate therewith and be ad-- vanceablein an upward direction thereon as the growing cop operates to displacesaid member in the reciprocationthereof with the rod 88. It is wellknown that the intermittent contact between the cop building means andthe cop, which is necessary in order to produce the advancement abovereferred to is likely, by the friction induced, to produce a burningof'the cop; and where the cop is rotated at an exceedingly high rate ofspeed,' as is so in the case of the lar attention should be given tothis part of the mechanism in order to prevent the burning of the cop.To this end, we have provided an impact device, adapted to be impingedby the cop and'preferably annular in form, so constructed with referenceto the surface portion thereof which impinges against the cop and in itsrelation to the member (comprising the thread guide) which is to beadvanced that-the said burning of the cop is prevented.

We will now proceed to describe the preferred form of our improved copbuilding mechanism which Figs. 28 to 30 illustrate. 93 is a thread guidemember (carrying a thread guide, as hereinafter explained) andcomprising a sleeve 94 which slides, freely on the rod 88 and an. arm 95projecting from the sleeve and penetrated by the rod 92. The arm 95 isformed with a ring 96 and in this ring is arranged an annular impactdevice 97 having an annular exterior flange 98 at its lower end and amilled nut 99 screwed onto its upper end and forming a flange whichcoacts with the flange 98 to limit the vertical movement of the impactdevice in the ring 96. The impact device is preferably formed of wood,or some such light substance, and its bore is upwardly tapering, as at100, being thereby calculated more or less closely to fit the conicalupper end of the cop; to enhance the grip which the impact device isdesigned to acquire upon the tapering end of the cop, the lower end ofsaid bore is preferably rounded or flaring, as at 101. The flanges 98and 99 are so spaced that they allow slight vertical movement of theimpact device in the ring 96; moreover, the impact device is of somewhat*less diameter than the interior diameter of the ring, allowing slightlateral movement of the impact device in the ring. Gravity, of course,maintains the impact device in the position shown in Fig. 29, its lowerflange being clear of the ring. When, therefore, in the relativereciprocation occurring as between the thread guide member and the copbeing wound, the cop impinges against the impact device, the latter isnot only free to adjust itself laterally (should the axis of the cop benot exactly coincident with that of ring 96) to the cop, but permitssome lost motion to occur before the tendency to produce advancement ofthe thread guide member begins to become operative. The friction on thecop which would otherwise occur (that is, if the cop directly engaged apart of the thread guide member which was not upwardly displaceabletherein and which was subject to the retarding influence of a more orless tightly fitted bearing), is thus very largely absorbed, so that,although the rotating speed of the spindle may be very high, theundesirable burning of the cop is not produced. In this connection, itshould further be remarked that since the impact device is freelymounted in the ring 96, and since the impacts between the impact deviceand the cop occur at frequent intervals, the impact device is usuallymaintained in a state of rotation, whereby the friction between the copand the impact device is materially less than it would be were theimpact device stationary each time the impact occurred. The thread guide102 is, in the present adaptation, an arm pivoted at one end on a screw103 and carrying an eyelet 104 at its other end. A projection 105 onthearm rests on a set screw 106 tapped into a projection of the sleeve andis engaged from above by a pin 107 which slides in a projection of thesleeve, a spiral spring 108 interposed between said projection andthehead 109 of the pin maintaining the pin against the projection 105. Thehead of the pin and the end of the screw are preferably rounded, asshown. By adjusting the screw the thread guide proper 'may beset at anydesired elevation to vary the diameter of the cop being wound. Toallowthe advancement of the thread guide member upwardly step by step, aplate spring 110, bearing atuts .upper end against the sleeve 94 andhavmg its lower end turned inwardly and engaging the notches in the rod88, is carried by the lower end of a lever 111 which is pivoted betweenits ends in the projections 112 of the This structure comprises twoparallel rods sleeve 94. Each increment of rise imparted to the threadguide member by the'growing cop is maintained by the engagement o-f thespring 110 with the notched rod 88; and when the building'of the cop iscompleted the lever 111 is pressed upon at its upper end so as todisengage the spring from the rod and allow the thread guide member tobe lowered. It will be noted that the spring 110 extends above the pivotof lever 111,

' so that it normally keeps the lever in the position shown in Fig.28,the spring being engaged with a'notch in rod 88. To determine thepoint from which the advancement of the member 93 begins, we provide astop 113 in which is swiveled a screw 114 tapped into a nut or block 115which slides in a guide way. 116 in thestop at. ri ht angles to the rod88 and has the face t ereof adjoining the rod serrated, as at 117, toengage the teeth of the rod. When the member 93 is manually releasedfrom rod 88 and slid down thereon into engagement with the stop, thelower end of spring 110 is accommodated in a recess 118 in the-stop.

The tension device 119 shown in Figs. 1, 2 and 31 is substantiallyidentical. with that shown in the patent to Wells No. 739523,

already referred to, so as ecitic description thereof and of its mode 0operation is not necessary herein further than to say that it comprisesa case- 120 having thread guides 121- which direct the portion of thethread between them over a plate 122 above which lie two or more rollers1.23 freely movable vertically and longitudinally of the thread.

As it is desirable, however, so to mount this 1 device that" it may beset at any inclination found necessary, a supporting structure thereforis provided which may be tilted.

124 mounted at their ends in brackets 125 into which are tapped at theircenters screws 126 passed'through the arms 0 and serving to clamp thesupporting structure for the several tension devices at any desiredangle.

The operation will be understood by those skilled. in the art Wt may bebriefly explained as follows: Shaft z, and consequently shaft 13 beinrotated, the cams 17 produce oscillations o the rail 89, and hence thereciprocation of the thread guide rods and the cop building mechanismscarried thereby, while the advancing belt rotates'the several spindles,to each of which the power is transmitted from the belt throughithecorresponding rotary transmission members comprising parts 67 68 and 69,the hook 82 having been engaged with the stop 84 so that the levelstructure comprising parts '73, 74 and 76 maintains the carrier for thetransmission member in the position where said transmis ber 93 depressedand in engagement with the stop 113 and as it proceeds, in thereciprocation of the thread guide rod 88, the growing cop from time totime produces a relativeupward advancement ofjthe member 93. Thiscontinues (the thread being meanwhile held-under uniform tension by thetension device 119.), until the arm 95 of the member 93 engages andraises the hook 82 which latches the lever structure in its normalposition. It will thus be disengaged from the stop 84, allowing thelever structure comprising parts 73, 74 and 76 to fall away from thecarrier 62 so that the carrier may follow with a corresponding movement,breaking the contact between 66 and 69. When the winding of anyparticular cop is completed and a fresh one is to be started, the

thread uide member 93 is returned into contact wit the stop 113 and thehook 82 drawn forward and rengaged with thestop 84.

It being remarked that the pitch assumed by the coils of thread on thecop depends upon the velocity of the rotary motion relatively to that ofthe transverse motion involved' in the winding operation, in our machinethis pitch may readily be varied by changing the relativepositions ofthe members 5 and 15 of the driving mechanism so that member 15 engagesmember 5 more or less near the greatest diameter of the latter.

Having thus full described our invention, what we claim an desire tosecure by Letters Patent is:

The combination, with a suitable sup port, of a member forming anaxial support for the body of thread to be wound, a thread-guide member,means for reciprocating one of said members substantially longitudinallyof the'axis of the first member and for rotating one of said membersaround said axis, one of said members be ing advanceable relatively tothe other substantially longitudinally of said axis, and an annular imact device adapted to impinge the body o thread being wound andrevolubly arranged in the thread-guide-member, said devicehaving limitedyet appreciable axis, substantially as described.

16. The combination, with a support, of

said members a lost motion in the latter'tran'sversely of said twocoactive cop forming members, one of said members afi'ording an axialsupport for the cop to be formed, means for rotating'one of said membersaround the axis of the cop supporting memberand for reciprocating one ofsaid members longitudinally of said axis, one of said members beingadvanceable relatively to the other longitudinally of said axis, and acop impact device carried by, and having limited yet 'appreciable lostmotion longitudinally of said axis in, one of said members,substantially as described.

17. The combination, with a support, of

two coactive coip-forming members, one of ording an axial support forthe cop to be formed, means for rotating one of said members around theaxis of the cop supporting member and for reciprocating one of saidmembers longitudinally of said axis, one of said members beingadvanceable relatively to the other longitudinally of said axis, and acop impact device carried by, and having lost motion laterally of saidaxis in, one of said members,'substantially as described.

18. The combination, with a support, of I a winding mechanism comprisinga spindle memberand a thread-guide member, the latter being engageablewith the cop being wound, one of-said members being rotative around theaxis of the spindle member and one being advanceable by the growing coprelatively to the other, a rotary driving part engaged with and normallymovable out of driving engagement with the spindle.

member, and means, comprising a fulcrumed part projecting into the pathof movement of the advanceable member, and a stop adapted to be engagedby said fulcrumed part, for normally maintaining the drlvmg part inengagement with the spindle member, substantially as described;

Intestimony that we claim the foregoing,
